IMPROVEMENT IN FOG-SIGNALS.

Specification forming part of Letters Patent N 0. 175,592, dated April 4, 1876 application filed January 8, 1876.

and Fig. 2 view of the post.

Like letters of reference indicate correspond ing parts in the difl'erent figures of the drawmg.

My invention relates, principally, to that class of fog-horns which are designed for use on shipboard; and consists in a novel construction and arrangement .of the parts, as

- hereinafter more fully set forth and claimed,

by which a more effective device of this character is produced than is now in ordinary use. The nature and operation of my invention will be readily obvious to all conversant with such matters from the following description.

In the drawing, A is the base, which is provided with three vertical standards or uprights, B, arranged equidistant from each other, and connected at their tops by the hoop O and pins D. Two end pieces or heads, K F, are arranged to slide vertically between the standards B, and are connected by the tubular bellows M, which may be formed of leather, canvas, or any suitable material for the purpose, and kept distended laterally by interior hoops I J, having guides L, which slide on the standards as the bellows are worked. The upper head F is provided with a circular central opening, (not shown,) covered by the hollow conical cap m, carrying at its apex an ordinary fish-horn or trumpet, r, preferably arranged in a vertical position. Projecting upwardly from the head F there are two posts or bars, G, to which are pivoted, at their upper ends, the pendulous links S. These links support the frame-work U, which is centrally pivoted thereto at T, and provided at one end with the handle'socket V, and at the other with the stud W. This stud is fitted into a socket ll one end of the. bar X, the other end being pivoted, by the rod y, in the slide Y, which is rendered vertically adjustable in the post a by the slots 3 and pins Z. A bent lever, N, provided with the socket Q, is pivoted in the standard P, attached to the base A,and has its horizontal arm 0 jointed to the under side of the'head K.

The post a is designed to be secured to the deck of the vessel or any other proper support, and the whole apparatus may be erected in any convenient position on board the ship in which it is carried.

In the use of my improvement the bellows may be actuated by the lever N or frame-work U by means of the handle R, which is so formed as to fit either of the sockets Q V.

When the lever N is used the handle is inserted in the socket Q, and the head F secured to the standards B by the pins H, the head K being left free to slide on the standards. If, now, the handle is oscillated or worked back and forth, the lever N will be rocked on the pivot P, causing vertical reciprocating movements of the head K, operating the bellows M and blowing the born 1", in a manner which will be readily understood from the foregoing description.

When, from any cause, it is more convenient to operate the bellows by means of the frame-work U, the pins H are withdrawn, and the head K firmly secured near the base A by means of the strings a n. The handle R is then inserted in the socketV and worked vertically, its center of motion being the pin y, and its fulcrum the pivots T, the head F receiving vertical reciprocating movements as the handle is elevated and depressed.

An ordinary bellows-valve (not shown) is provided for the ingress of air to the bellows M, the air, in its ingress, being concentrated at the horn by the cone m. It will be obvious, however, that the cone maybe omitted, if desired, and the horn attached directly to the head F.

Having thus explained my invention, what I claim is 1. In a fog-horn, substantially such as described, the base A, standards B, heads KF, X, handle R, and post a, constructed and arbellows M, horn 1', pins H, lever N, and hanranged to operate substantially as and for the rlle R, combined to operate substantially as purpose specified.

and for the purpose set forth and specified. PAUL E. COLLINS. [L. S]
